To all whom it may concern:

Be it known that we, WILLIAM E.'HUB- BELL and WILLIAM MORRIS, residentsof Alton, in the county of Madison and State of Illinois, have inventedcertain new and useful Improvements in Leer-Charging Apparatus, of whichthe following is a specification.

The general purpose of this invention is to rovide mechanism at theinlet end .of the eer for conveying the ware thereinto from the shopwhere it is pressed or blown and depositing the same on the leer ans,thus dispensing with the carrying-in oys now generally employed to dothis work. While designed primarily for transferring bottles, the

invention is not thus limited. An objection to mechanisms heretoforeproposed is that they occu y considerable room at the inlet end of theleer and are much in the 'way, both when in and out of operation. Onepurpose of the present in vention is to so construct and arrange theapparatus as to occupy comparatively small space outside of the leer,with the exterior 'portion' of the mechanism adapted to be,

placed in a depression in the floor and entirely out of the way when theshop which it is serving is idle, thus leaving the floor clear andunobstructed.

Primarily, the invention is embodiedin a conveyer upon which the resserand blower deposits the ware and w ich moves it forwardly into the leer.Within the leer is a carrier which moves transversely of the leer pans.Mechanism of improved construction is employed for transferrin the warefrom the conveyer to the carrier, t e-arrange ment'being preferably suchthat the ware is assembled in rows on the transverse carrier.

elm-Upon the completion of each row, mechanism operates to move the samefrom the car-- ner, thus assembling at one s1de of the latter a numberof rows, and when the accumulation 'is sufficient to fill a leer pan,mechanisrii operates to transfer the same onto a pan,-

and the pans are then advanced in'the leer in the usual manner, placinan empty pan in position to be filled.

preferably such that the pan filling operation 60 is accomplished by thepacker at the. dis

charge end of the leer, thus making it 'unnec-.

Figs. 6 and 7 are detail views of one ofthe pivoted ware supports. Fig. Sis a-longitudinal sectional view of themechanism for transferrin the ware from the transverse carrier to t eleer pans, and Fig. 9 is a similar view of the same mechanismillustrating the mode of seating the ware on the leer pans. Fig. 10'is adetail view of the sliding transfer late shown in connection with oneofthe eer pans. Fig. 11 is a diagrammatic view of the mechanism extendingto the discharge end of the leer for operating the transfer mechanism atthe inlet end thereof. Fig. 12

is a detail view of the ratchet mechanism for 1 moving the transversecarrier.

- Referring to the drawings, the mechanism folrcarrying the ware from'ashop into the inlet end of the leer has its main ortion arranged atoneside'of the interior of t e latter, this inner portion consisting of theupright frame 2, with stand 3 at the inner end and in line therewitlnThe factory 'floor 4 in front of the leer'has a depression or channel 5of sufficient width to permit the conveyer and ware supports to traveltherein. An upright 7 is hinged at its lower end in this depression at8, and is held in upright position by the adjustable tie-rod 9. 10 isthe carrying-in conveyer chain, the outer portion of which passes aroundthe sprocket wheels 11 and 12 at the u per and lower ends, respectively,of standar 7, with the Ware carriers 13 so pivoted to the chain as toalways hang in u right position. Between upright '7 and t 1e leer theconveyer travels in floor depression 5, the upper course of the chainbearing upwardly against rollers 14 on the trapdoor 15 which closes aportion of the floor depression. When the apparatus is not in use,

stay 9 is released and upright 7,;rarrying the outer portion of theconveyer is turned downward into the depression and trap 15 closedthereov'e'r, thus clearing the floor of this portion oLthe mechanism.When'the mechanism is thus turned down, the outer normally open portionof the floor deprestra v1 by trap 16, similar to 5'. 1 J. ithin theleer, the upper and inwardlytraveling portion of chain 10 passes oversprocket 17, and beneath horizontal bar 18,

Y and over the large sprocket'wheel 19 journaled in stand 3. From thiswheel the chain passes downwardly andoutwardly into the floor.depression and tosprockets 12 and 11.

' Each of the depending pivoted sup orts wall 13 on chain consists'of arear vertic 20,' with the centrally arranged chain connecting pivot 21at its upper end, while at the lower edge thereof is the laterallyprojected ware supporting floor 22. Hin ed to the rear edge of floor 22is the angular older 23, wei hted at oneend at 24 to hold it in inturneposition for confining the bottle or other ware on the laterally openfloor 22.

. This holder operates in conjunction with the curved guard 25 securedto and raised from the-outer portion of bottom 22 and against which theforward side of the bottle is held. 26 is the linked belt-liketransverse carrier which passes around the path of the leer ans 27 on.sprocket wheels 28 and 29. Wheel 28 is secured to shaft 30 journaled atthe inner side of frame 2, while wheel 29 is mounted in any convenientmanner at the opposite side of the leer. The pivoted ware supports 13pass upwardly and inwardly along the inner side of frame 2 and in closeproximity to the receiving end of carrier 26, as clearly shown in Fig.4. It will be understood that, carrier 10 moves continuously thoughrelatively slowly, the power being imparted throughdrive-chain 31extending from a s rocket on the shaft carrying v sprocket-w eel 19 tothe sprocket-wheel 32 on drive shaft 33 at the exterior of the inlet endof the leer.

. .up or inward y moving course of the latter,

an slidable therein is arm 35 carryin at its inner end the two dependingwing,- 'ke lades 36 and 37 arranged atright angles to each chain 10and'towar other and directly in the ath of carrier 13. Wing 37 extendslon' itu ally of conveyer the approachin ports13,'and'the-arrangement issuch that the upright portion 20 of each support moves behind this wingso that the rounded extremity 38 of the latter engages holder 23 on theware support and turns it outward, thus releasing the bottle. Wing 36is'open at 38 to permit guard 25 to pass. therethrou h. When eachcarrier 13. (spaced at equal distances on-chain 10),.comes to positionopposite the pushing device, with wing 36 of the latter immediately infront of the bottle sup- .plate-hke sup ort extending from leer pans 27.

and wing 37 behind it, the slide- 35 is moved inwardly into the positionshown'in Fig. 4 and shoves the bottle from floor 22 of the support ontocarrier 26. After the bottles are removed from supports 13 and as thelatterpass downwardaround sprocket wheel 19, the outturned holders 23are engaged by trip 3 on stand 3 and turned inward into bottle-holdinposition, ready. to receive another artic e and carry it into the leer.

For actuating slide 35, a vertical rockshaft 39 has a horizontal arm 40extending between roller studs 41 on the upper surface of the slide,while another arm 42 carries a roller stud 43 which moves in theirregular or oflset groove 44 in thetop faceof sliding plate 45. Thisplate -moves in slideway 46 formed on frame 2, and has one end connectedby link 47 with crank arm 48 on the horizontal rock shaft 49. Securedtothe inner end of this rock-shaft is arm 50 which extends upwardly inclose proximity to the path of chain 10 where it is engaged byprojection' 51. These rojections are arranged at. such points on thechain as to efiect the inward movement of ware-pushing slide 35 eachtime a sup ort 13 is'in position to discharge the bott e carried therebyonto carrier 26. Arm 50 is of such length as to be released by rojection51 after shaft 49 has been rocke the distance necessary to operate thepushing mechanism, whereupon the latter is returned to normal positionby the weighted line 52. I

Endless carrier 26 is moved intermittently by means of ratchet wheel 53secured to shaft 30 on which shaft wheel 28 is also secured.

54 is an arm which turnsloosely in shaft 30 and is embraced by an arm 55on. rock shaft 49, so that each time the rock shaft is oscillated bycarrier chain 10, arm 54 is lifted and dog 54 on said arm and'inengagement with the ratchet turns shaft 30 and advances car- 'rier 26 adistance sufiicient to give room for the bottle then being ushed ontothe carrier. Obviously, upon the ackward movement of shaft 29 inresponse to the pull of weighted line 52, arms 55 and 54 move downward,giving the dog,54' a fresh hold on the ratchet for the next operation.

The transverse belt-like chain 26 moves over the separated plate-likeguides 56 and 57 supported above the leer pans 27. 518 is a i e 56toward the et end of the leer, w e project' in the o posite directionfrom guide 57 is t e inclined fixed su port 59. Cooperatinglwith su port59is the transfer plate 60 whic normally forms an inclined extensionthereof, with its outer edge resting on the Pins 61 at opposite sides ofthe raised rear edge of plate 60 are entered in the'inclined grooves 62formed in the outer extremities of arms 63'of the ulling device 64,whichis slidable longitu ally of the packer for advancing the leer pans.

the leer by a chain working over sheave 66, and extending from thelatter to the other end of the leer where it is connected to mechanism67 of well known construction leer as they are loaded at one end andemptied at the other. This movement carries the ware last deposited outof the way of the charging mechanism. The same movement also operates toretract plate 60, slots 79 in the plate being engaged by the taper whichis operated by the leer tender or I lugs 80 on the leer pans so thatplate 60 is This mechanism enables the packer to operate drawn inwardwhen the pans are advanced. Plate 60 rides up on the fixed inclines 81and plate 60 at the required times for depositing l is thus disengagedfrom lugs 80 and is free the bottles onto the leer pans, as willpresently appear. a

68 is an arm pivoted at one end to support 58, and at its free endlooped downwardly at 69 with its extremity 70 in the path of projections71 on chain 10. A pin 72 on the looped arm extension 69 is embraced bythe upper extremity of lever 73, while loosely connected to the lowerend of this lever is a second lever 74 whose lower end is in the path ofpin 75 on chain 10. 76 is a push bar slid able on support 58 with links77 connecting it with the pivoted arm 68.

With the mechanism in operation, when carrier 26 has become loaded witha row of ware which extends across the leer pans, arm 68 is engaged bypro 'ection 71 on chain 10 and the arm is so oscillated as to move pushbar 76 across the carrier, moving the ware therefrom onto support 59,and at thesame time advancing the foremost ware previously placed onsupport 59 onto the inclined plate 60. When ar 76 has moved sufficientlyto push theware off of carrier 26 the fixed incline 78 depresses thelooped portion 69 of bar 68 out of engagement withchain projection 71,thus freeing the pushing device of further forward movement.

is to lower pins 61 in 'slots 62, permitting plate 60 to rest flatly onthe leer pans 27, with only the thickness of the plate separating theware from the leer pans. I A further backward or outward movement ofsupport 64 operates to draw plate60 beneath the fixed supports 59, and58 and beneath the upper course of carrier 26, and with the outer edgeof support 59 operating as an abutment for the ware, the'continuedbackward movement of plate 60 causes the ware to be shoved therefromonto one of the leer pans. The latter are then advanced through the leerthe length of a pan as is ordinarily done when moving thepansprogressively through the i for the next operation.

At this juncture, a pin 75 on chain 10 engages the been thus returnedinto the leer, pins 61 are in the lower ends of slots 62, with the plate60 resting flatly on the leer pans, and it is only necessary to shovethe pulling device 64 inward slightly in order to raise pins 61 in theinclined slots and place the edge of plate 60 in line with the outeredge of the fixed support 59.

It will be understood that the several pins or projections on chain 10are so spaced apart as to properly time the sequence of operation. Withthe, mechanism arranged as here shown, the whole apparatus ismanipulated by the ware packer at the discharge 'end of the leer, thecharging mechanism operating automatically to place the ware on thetransverse carrier and to advance it from the latterone row at atimetoward and onto the inclined plate whichfinally transfers it to theleer pan;

Several leers are usually arranged side by side, andin such a case shaft33 may drive the charging mechanism for all, the individual clutchdevice 82 for each mechanism operating to place the same in and out ofoperation as required. Obviously, however, various forms of drivingmechanism may beprovided.

With the improved mechanism in. service, there isno necessity forhandling the ware from the time it is deposited by the blower orp-resser onto one of the supports 13 until it is finally removed by thepacker from theleer, all of the manipulation incident to carrying itinto the 'leer'pans being accomplished automatically.
